Abstract
A trolley for moving heavy objects such as wire coils from a machine to a container at a packaging table is provided. The trolley includes spring-loaded spaced arms movably mounted for vertical height adjustment so that the arms are just below the coil when it is on the machine and rotational movement to separate the spaced arms with the spaced arms retaining the heavy object during movement of the trolley apparatus, and locking arms engaging the spaced arms during movement of the trolley apparatus to prevent separation thereof. The spring-loaded arms permit the heavy object to be manually pushed downward therebetween, thereby forcing the arms apart enabling the object to fall from the trolley into a container on a packaging table. The table includes a platform for supporting the container, a motor for raising/lowering the platform, and a mechanism for retaining the container and aiding its alignment with the coil.
